Abstract

This paper deals with robust optimization and network flows. Several robust variants of integer flow problems are considered. They assume uncertainty of network arc capacities as well as of arc unit costs (where applicable). Uncertainty is expressed by discrete scenarios. Since the considered variants of the maximum flow problem are easy to solve, the paper is mostly concerned with NP-hard variants of the minimum-cost flow problem, thus proposing an approximate algorithm for their solution. The accuracy of the proposed algorithm is verified by experiments.

具有不确定圆弧容量的整数流问题的鲁棒解

本文主要研究鲁棒优化和网络流问题。考虑了整数流问题的几个鲁棒变体。它们假定网络电弧容量和电弧单位成本(如适用)的不确定性。不确定性由离散情景表示。由于所考虑的最大流问题的变体易于求解，因此本文主要关注最小代价流问题的NP-hard变体，从而提出了求解它们的近似算法。通过实验验证了该算法的准确性。
